> my question is "why do you need to set up the third party linters when they're so critical to the correctness of your program" really.

No doubt the same reason it is also critical in Haskell (see comment about isLoggedIn function): Developers not knowing what they are doing.

If you work within the idioms and generally accepted programming practices this isn't a problem. It only becomes a problem when you get a developer who wants to "go their own way" without understanding why the norms exist. The linter is a crutch to support their "bad habits".
